Swing-up of quantum emitter population using detuned pulses
Thomas K. Bracht, Michael Cosacchi, Tim Seidelmann +5
The controlled preparation of the excited state in a quantum emitter is a prerequisite for its usage as single-photon sources - a key building block for quantum technologies. In th…
Deterministic photon storage and readout in a semimagnetic quantum-dot--cavity system doped with a single Mn ion
M. Cosacchi, T. Seidelmann, A. Mielnik-Pyszczorski +6
Light trapping is a crucial mechanism for synchronization in optical communication. Especially on the level of single photons, control of the exact emission time is desirable. In t…
-photon bundle statistics in different solid-state platforms
M. Cosacchi, A. Mielnik-Pyszczorski, T. Seidelmann +4
The term -photon bundles has been coined for a specific type of photon emission, where light quanta are released from a cavity only in groups of particles. This emission lea…
Time-dependent switching of the photon entanglement type using a driven quantum emitter-cavity system
Tim Seidelmann, Doris E. Reiter, Michael Cosacchi +3
The cascaded decay in a four-level quantum emitter is a well established mechanism to generate polarization entangled photon pairs, the building blocks of many applications in quan…
Accuracy of the quantum regression theorem for photon emission from a quantum dot
M. Cosacchi, T. Seidelmann, M. Cygorek +3
The quantum regression theorem (QRT) is the most-widely used tool for calculating multitime correlation functions for the assessment of quantum emitters. It is an approximate metho…
Numerically exact open quantum systems simulations for arbitrary environments using automated compression of environments
Moritz Cygorek, Michael Cosacchi, Alexei Vagov +4
The central challenge for describing the dynamics in open quantum systems is that the Hilbert space of typical environments is too large to be treated exactly. In some cases, such…
